T o all whom it may concern:

Be it known that I, Josnrii BARRAJA- I .FiL-iUENrELDnR, a citizen 'of the United .ments in Submarine Boats, of

States, residing at Bridgeport, in the county Yof Fairfield and State of Connecticut, have invented certain new and useful Improvewhich the following is .a specification.

Modern submarine or submersible torpedo boats are so increasing in size thatit is'v found impi'acticable to .handle tlicusual hand' operated valves now employed for controlling the admission of sea-water into lthe main ballast-tanks so as to 'bring the boats from the surface to the awasli condition within the specified time for effecting this operation, this being due to the fact that the larger types'of boats possess greater surface buoyancy, necessitating larger ballasttanks, and relativelylarger sea-valves, in

:order .to trim the boat forsubmergence Withtwo openings controlled by outwardly op'enl ing hand operated sea-valves, and also o pening into the ballast-tank through. a single opening cont-rolled by anV inwardly opening I and preferably power4 operated valve of an the sea-valves are area substantially equal to the combined area of the two sea-valves, the construction, arrangement and operation being such that first .opened by hand power operated devices to admit water into the manifold. when the boatis being `made' from which.

ready for submergence, and manifold the water may quickly be admitted to the ballast-tank when the moment arrives to put the boat 'into submerging condition, that is to say, into ,condition ready for final trim and complete` submergence.

The invention further consists in the peculiar and novel features of construction,

combination, and arrangement of parts as will be hereinafter fullydescribed and thenv claimed.

In the drawings illustrating the invention,

1 designates the outer hull of a submarine or submersible torpedo boat,I and 2 the inner or main hull thereof. -The space Btlius formed between said hull section is divided by transverse partitions "or bulkheads 3 providin a water ballast -compartment commonly known as a tank, and in the present construction constitutes thel'main ballast-tank. It maybe stated 'here` that While my invention lis illustrated in connection with a double hull boat, it is not to be understood thatI limit myself to this design of hull, as the invention will be foundv equally ,applicable to single hull boats in which the main ballast-tanks are built within the'main hull. Within thetank 3, and connected airand water-tight to the hull. sections 1 and 2, is a manifold 4 having a horizontal partition 5 providing. an upper chamber 6 and a lower chamber, the latter being divided by vertical longitudinally arrange-d partitions 7, which are connected airand Water-tight to the plate of the outer hull 1, providing a central duct 8 in open communication .at its ends with the ballast-tank 3, and two e'nd compartments 9, which. are closed at their sides and in open communication with the water of flotation through openings 10 formed `in ythe plating of the outer hull 1.

The compartments 9 commanicate with the chamber 6 through openings 11 formed in the said horizontal partition 5, and are controlled by outwardly opening sea-valves' 12, the stems 12 ofwhich extend upwardly through the partition 5, andl through stalling-boxes 13 connected thereto, and

have theirl upper' ends terminating in slotted heads 1.11 providing traininels. As

the headl of each valve stem and the mechapartition 1,91 arranged in the inner or mainhull section 2 of the boat. Keyed upon the shaft 17, at each side of the head 141, are lever-arms 19 in the free ends of which is vjournaled a short shaft-19 carrying a camhlock 2O which is designed to'operate in the horizontal end of the cani slot 15, andupon one end of the' shaft 17 is keyed a segmental worm-wheel-21\which isineshed by a.-

dr'ive-worni 22 carried by a shatt 2d jour naledat its lower end in a bearing 24 secured to the lower side of the partition 191, and

having itsupper end extended through said partition and mounted. in a suitable bearing 25 mounted upon the top ot the said partition 191, and proyidedwith a hand wheel 26. By the mechanism just described, it will be apparent, that as'the shafts 23 arerotated in one direction or the-other, the seg- L but little energy.

mental worm-wheels 21.will be rotatedto thus cause the cam-blocks 2O to slide 'in the horizontal end 15 of the cam slots to thus impart a vertical reciprocating motion to the valve stems to open or close the valves 12, as the case maybe. lt will also be apparent that by thus gearing the operating shafts to the valve stems I obtain great leverage, and hence, ain enabled to operate the if'alves with ll-he' channel or duct 8 communicates with. the chamber 6 through an opening` 8 formed i in the partition 5, the opening being -controlled by an inwardly opening valve 28 to which is swiveled the lower end ot a pistonrod 29 carried by a piston 29 operating ina cylinder 30 mounted in the main hull section 2 below the partition 191. The lower end of the rod 29 operates through a stuffingboX 31 secured to the top 4 oi the manifold and has its upper end extended through. the head of the cylinder 30 and through a stud'- liig-box formed thereon, and itsl extreme upper end threaded as shown at 31 Fig. .7 for the purpose hereinafter appearing. Fluid under pressure, which may be air, oil,

or water', is admitted to the opposite ends of to flow into the ballast-tank.

the cylinder 30 through a branch pipe 30 I Fig. 3 extending from a suitable source of 'supply (not shown) and in which is arranged a two-way Valve 80", which, for convenience of illustration. is shown located ad jacent to the cylinder, but -which may he arranged in the centi-al control station, or conning-tower, or in4 any other convenient' place within the boat. It 'will be understood that when fluid under pressure is admitted to the lower end of the cylinder 30, the val-re 28 lwill be lifted from its scatto thus permit the water in the chamber 6 of the manifold ln ,order to operate the valve 291 by hand in the event of accident to the power operat ing devices, inount a threaded sleeve B1 uponthe threaded section 31 oil" the piston rod and upon the peripheryot the slee-re l mount a worin-wheel 32 which is hold against vertical 'increment by a braf'flret- 559i extending from' the head of the cylinder 89. and by channel bars 34 secured to the lower side of the partition 191. The hub ot the worin-wheel 32 is made in sections and comprises a. seinhcircular section 35 Fig. 6 which is formed integral with the rini oitv the wheel and a loose section 3G which is carried by bolts -37 extending through diametrically disposed ribs or spokes connecting the rigid 1 section of the hub with the rim of vthe wheel.

said bolts having clamping nuts threaded upon their outer ends by which the loose section of the hub may be clampedy against the sleeve and the wheel thus clamped upon the sleeve so as to cause the sleeve to rotate with The worm-wheel is ineshed by a worin 38 mounted in a bracket 39 aupported by the partition 191 and has its shaft provided with a hand wheel 40, Figs. 3 and l. By this arrangement it will be evident that when the wheel 32 is clamped uponlthe sleeve andthe worin 3S is operated. the sleeve will be rotated' and because said'sleeve and the wheel 32 are held against rei-tical movement.

' the Valve 28 will be opened or closed as the caseinay be.

lnorder to prevent the operation oi' tnevalve 28 until after the sea-valves 12 have been opened l connect the stems oi" the sea- :that when 'the -val'ves 12 are opened the l.

elbow levers i1 will be rocked in the direc tion indicated by the arrows in Fig. 9, te thus withdraw the ends of the locking pin`l or rods from the groove 4i in the pistonood so that the valve 28 then inay be opened.
